Plastic bearings: its type and advantages over metal
2024-07-24
After all, they may be used in rugged products and subsystem components, such as bearings made of alloys such as steel and bronze. Or they simply don't think plastic can handle harsh applications or extreme environmental conditions. But the fact is that modern plastic bearings (especially plastic ball bearings) can withstand extreme temperatures, heavy loads and high speeds. However, it is importa...

Why do injection molded parts develop sink marks and dimples?
2024-09-02
(1) Improper control of molding conditions If the injection pressure is too low, the injection and holding time is too short, the injection speed is too slow, the material temperature and mold temperature are too high, the cooling of the plastic part is insufficient, the temperature is too high during demolding, the temperature around the insert is too low, or there is insufficient material supply...

(Ⅲ) How to deal with flow marks on injection-molded parts?
2024-09-27
Mold temperature too low Cause: The low mold temperature causes the molten plastic to cool too quickly in the runner, preventing full fusion. Solution: Increase the mold temperature to ensure the molten plastic flows smoothly and fuses completely. Injection speed too slow Cause: Slow injection speed causes the plastic to flow slowly, extending cooling time and forming weld lines. Solution: Increas...

The application of high-performance long glass fiber (LFT) materials in explosion-proof cameras
2024-10-28
As we all know, explosion-proof products have extremely specific requirements—explosion-proof ratings, material standards, sealing performance, functionality, certification requirements, and more. Among these, material requirements are particularly stringent. Taking explosion-proof cameras as an example, most currently use stainless steel or cast aluminum alloy for the casing, which can withstand ...

Overview of 8 Non-Destructive Testing (NDT) Methods for Composite Materials
2024-11-01
Composite materials are new materials created through advanced material preparation techniques that combine components with different properties in an optimized manner. In the 1940s, due to the needs of the aviation industry, fiberglass-reinforced plastics (commonly known as fiberglass) were developed, marking the beginning of the term "composite materials." After the 1950s, high-strength and high...
